In vitro characterization of mucoadhesive polysaccharide polymers tablets fabricated using FTIR press

In vitro of some bfactors affecthng the adhesive strength of mucoadhesive polymers

Mucoadhesive durg delivery systems are among novel drug delivery systems that due to their ability to adhere and remain on the mucosal surfaces and a show and sustained release of their drug contect have attracted special attention in recent years.the aim of this study was to evaluate the effect of four different important factors on the  mucoadhesive strength of a few  mucoadhesive polymers.am...

In-vitro Absorption Studies of Mucoadhesive Tablets of Acyclovir

In this work, the dissolution-absorption studies were conducted on marketed tablets of acyclovir (ACIVIR-200mg) and the mucoadhesive tablets of acyclovir using varying concentration of sodium lauryl sulfate as a permeation enhancer. The purpose of this study was to improve the absorption of acyclovir using sodium lauryl sulfate as permeation enhancer. The everted and perfused intestine model wa...

Formulation, Characterization, in Vitro, in Vivo and Correlation Study of Mucoadhesive Sustained Release Tablets

Preparation of Alprazolam Extended- Release Tablets and In vitro Characterization

Abstract The main aim of this study was to prepare and evaluate the extended - release system of an anxiolytic substance. Alprazolam is a short-acting benzodiazepine with general properties similar to those of diazepam. Our studies focused on the development of extended drug delivery system based on Hydroxy Propyl Methyl Cellulose (HPMC 4000cps) as retard agent and polyvinylpyrrolidone (PVP k30...

Preparation and In Vitro Evaluation of Sustained-Release Matrix Tablets of Flutamide Using Synthetic and Naturally Occurring Polymers

Frequent dosing of the potent anti-androgen, flutamide, is necessary to reach a therapeutic level for the treatment of prostatic carcinoma. Sustained delivery of the drug could reduce the adverse effects such as gastrointestinal disorders and improve patient compliance. In the present study sustained-release matrix tablets of flutamide were prepared by direct compression method using different ...
